[0032] The redirection column 4 rotatably connected to the connecting tee 5 is provided with three through grooves, which are interconnected and respectively connected to the connecting pipe 9, the first gas pipe 6 and the second gas pipe 7;

[0033] The two ends of the connecting pipe 9 are fixedly connected to two high-pressure gas storage tanks 10 respectively; a connecting shaft 3 is fixedly connected to the middle of one end of the redirecting column 4, and the end of the connecting shaft 3 away from the redirecting column 4 is fixedly connected to the hand wheel 1, and a handle 2 is provided on the side of the hand wheel 1 away from the connecting shaft 3; the redirecting column 4, the connecting shaft 3 and the hand wheel 1 are arranged in concentric circles; the ends of the first gas supply pipe 6 and the second gas supply pipe 7 away from the connecting tee 5 are fixedly connected to the air nozzle 13 respectively;

[0036] By adopting the above technical solution, the components in the box 14 will generate high temperature during operation, and the heat dissipation holes 16 on the top of the box 14 and the heat dissipation plate 17 at the bottom of the box 14 can dissipate the high temperature in the box 14 to the outside, but the heat dissipation efficiency of the heat dissipation holes 16 and the heat dissipation plate 17 is limited. When the temperature in the box 14 becomes higher and higher, the components in the box 14 will spontaneously combust under the influence of high temperature; the thick smoke generated by the fire will float in the box 14, and the smoke detection head 12 in the two compartments of the box 14 can detect the smoke. When the smoke detection head 12 detects the smoke, it will send out information, and then the staff can use the inert gas in the high-pressure gas storage tank 10 to extinguish the open fire in the burning compartment.
